Icklesham's historic roots can be traced back to 772, when it appeared as Icoleshamme in a land charter signed by Offa, King of Mercia. Strategically located on the River Brede, it was a prime target in the Norman invasion of 1066 (some 700 years later, evacuation plans were prepared in case of an invasion by Napoleon). The 12th-century parish church is dedicated to St Nicholas.
